However for one problem I needed to implement persistent segment tree with100000100000values in the leafs, and two long long values in each node while the memory limit is only6464megabytes. Firstly I created version that works with pointers, however later I replaced the pointers with integers repr...

The slides arehere I hope they can be useful for some of you. Any feedback will be very welcome, also if any of you know some good persistent segment tree problems on the codeforces platform, then that would be helpful. data structures,persistent segment trees,segment trees,tutorial ...
Hello, Recently, I've been learning about the persistent segment tree. However, is there a way to get a persistent segment tree with range updates, and not just point updates? If so, can someone direct me to a clean and easy implementation in C++? Thanks! -dx24816...
Thank you for your time. I think you are talking about using a merge sort tree, I tried using that but it exceeds time limit. Also, I am finding rank of k in array and to do that I am assigning it the rank of the last element that is not greater than k in the array, I think...
feodorv i dont think so cc is the value in left tree cnt is value i need if left can give me what i want, i go towards left anyways will it pass upto case 10 with such a blunder? thanks for ur help!! → Reply Codeforces (c) Copyright 2010-2025 Mike Mirzayanov The only programmi...
1. Positions at which there is an element shall have value1, others shall have0. In addition to the two pointers, each array node will also store the sum of all values. Basically our structure looks a lot like a persistent segment tree. This will allow us to implementlower_boundand...
Hi, everyone! I need some problems, which can be solved with Persistent data structures (It doens't matter what data structure as long as it is persistent). I searched but the only thing that I was able to find was this —http://blog.anudeep2011.com/persistent-segment-trees-explained-wi...
explain how to make convex hull optimization fully persistent. Even though the persistent version consists of a very natural extension of the original data structure I couldn't find anything with a quick search on google, therefore i decided to share it with the codeforces community. So here it...
